I have not seen blue smoke "yet." I think most of these 2014 summits are SICK! Chrysler needs to recall all of them! A buyer shouldn't have these type of problems with a new 52,000 dollar Plus vehicle.

Purchased a 2014 limited today with 20s and have the shimmy at 65 also. I actually test drove one with 18s before going with the 20s to make sure it didn't have any shimmy problems and it was fine. Wish I had test drove this one too. Had the same problem after buying a new 2006 Dodge Ram and went thru all the hassles of force balancing, drive shaft, changing tires etc... wound up doing a lemon law claim because they could never correct and claimed it was the "characteristics" of the vehicle. Give them 3 chances to fix and make sure you get a receipt for every attempt. After the 3rd attempt contact a lemon law attorney who will give them notice for their 4th and final attempt and proceed with lemon claim. In most states it won't cost you a dime other than time you have to wait (probably 6 months to a year, but worth it

Has any body resolved vibration issues with the 4X4 and 20" wheels.
I have been to the dealer 8 times , I tried a different brand of tires I purchased and the vibration is still there ?
I realize the Goodyear Fortera is a cheap tire , I don't think that is the problem.

Hi there,
I just bought a 2014 Overland and I had the same issue, when I was driving home from the dealership. I only have about 600 miles on it now and the issue seemed to have resolved itself after the first 100 miles or so. I am not sure how many miles you have but I can understand your frustration!

I have 2000 miles on my Limited with the 18" wheels and Michelin Lattitudes. My shimmy still persists between 60-70 mph. Frustrating!

Well, I went to dealer for the 1st attempt at fixing. They balanced all four tires and the shimmy is gone. Hopefully, it will stay that way. I will report if it comes back but so far 300 miles later it is fine.

I have 3800 miles on mine , the tires were just put on last week , the dealer installed the Goodyear again. I purchased the Firestone Destination just to try them and it didn't change anything.
Have you also experienced bump steer , this is when you hit a rut or pothole with the right front tire the steering wheel kicks back?
I am going to try to get Chrysler to do a buy back or lemon law.
I have two case files with Chrysler . I figure 8 times at the dealer is more than enough .
I am curious is it only 4X4 vehicles ?

For those with this issue: It is unlikely that it is a driveshaft or driveline issue. At least not directly. Symptomatically, an imbalanced driveshaft or a driveline phase issue (still possible with CVs) will show a cyclical, high-frequency vibration which is notably different from the described symptoms. It would be exceedingly rare to cause a steering wheel shimmy given the driveline setup.

More than likely it's a tire/suspension combination issue. Certain suspension tunings can exacerbate any tire imbalance or out-of-round condition. A suspension system can have certain natural frequencies of resonance--that can occur in both the high and low frequency domain. If one of those frequencies is within the range of certain tire RPMs it will act minimally damped and you'll get a vibration as well as a steering shimmy. Speaking of which, you can also have feedback resonances in the steering system which will cause a shimmy by the same principle.

So the likely cause here isn't driveline. It's more likely caused by the current suspension tuning setup and possibly steering feedback. Some vehicles will be much more sensitive than others based on numerous variables: tires (the amount out of round or balance they are--EVERY tire is slightly out, some worse), component tolerances, bushing tolerances affecting natural motion slightly, etc. Stack-up the tolerances just right and you'll have a vehicle that is REALLY sensitive and almost impossible to keep from vibrating.

Interestingly, this seems (looking at the statistics) to be more tuned to the air suspension (Quadra-Lift) than anything else. That suspension will have a different natural frequency than the standard suspension.

Agree with you on tires potentially being out of round. On past cars what I have found is that going with a tire rated for a higher speed can make a difference a V rated all season tire like the BFgoodrich Dueler H/L Alenza 265 50 20 or others can help because they meet a tighter spec to be V rated than these T rated forteras. No guarantees but moving to a higher speed rated tire has helped me on past cars with similar issues on theses larger diameters rims.

Just purchased and picked up today. Just drove 1st 200+ miles and had a vibration that was driving me nuts in the steering wheel and looked for a site with comments.. Here I am as I see others have same issues.

Vehicle
2014 Jeep GC Overland with V-6 Gas.

Strange as it seemed to come and go during the 100-200 miles driven. Then came back
